定期测量绝缘电阻，检查机壳接地情况。
Periodically measure insulation resistance, inspect motor sheath grounding.
检查一下控电板和设备体上的那些电器设备，看看他们的绝缘电阻和绝缘强度是否合格。
Check whether the insulation resistance and the dielectric strength of the electric devices attached to the panel and equipment body are sufficient.
检查电动机的绝缘电阻是否在正常范围内，运行时有无异响、温升是否正常；
Motor check whether the insulation resistance in the normal range, running any abnormal sound, temperature normal;
检查方法是将兆欧表上的一个接线柱接在电泵电缆线上，另一接线柱接在电机外壳上，摇动兆欧表，观察绝缘电阻值。
Megohm inspection method is to form an electric cable terminal at the online access, another access terminal on the motor casing, megohm shake table to observe the value of insulation resistance.
